Preheat the oven to 350 degrees F. For the crust, combine all the ingredients in a food processor, or combine them well by hand. The butter will still show in the dough.
On a nonstick surface, such as parchment paper, on the top and bottom of the ball of dough, roll out the dough with a hand roller so that it can fit into a pie dish (8 or 9 inches in diameter). Lift the crust up using the paper edges and place it in the pie dish. Alternatively, you can place the pie plate over the crust and flip the paper, crust and pie dish over, and then smooth out the crust in the pie dish.
Bake the crust for about 15 minutes, or until browned.
Next, for the lemon filling, add the egg yolks, lemon juice, and honey to a double boiler or other bowl that can sit on top of boiling water. Simmer the lemon mixture for about 10 minutes, stirring occasionally, until it turns thick and creamy, and yellow. It will resemble lemon curd.
Cool the lemon mixture to room temperature. Meanwhile, beat the egg whites until they have stiff peaks.
Fold in the creme fraiche and the egg whites into the cooled lemon mixture.
Pour the filling into the cooled crust, cover the pie dish and place it in the freezer for a few hours. It can be served frozen or thawed for 15 minutes. It also tastes light and creamy when stored in the refrigerator. I eat it at any temperature!
